Driving distraction is considered to be one of the main contributing factors in casualty crashes. Many methods were proposed to measure driver distraction. The effect of secondary tasks on situation detection was examined in this study. The ability of a stable driving when approaching a risky situation was assessed using a fixed driving simulator. The participants were required to drive in the virtual urban environment which included one risky situation under two conditions. The first condition was a normal condition in which the drivers only needed to drive without interference (control group). Meanwhile, the other condition requires the drivers to calculate the sum of two numbers while driving (experiment group). The lateral operation performance was measured by the driving simulator. The lateral deviation in the lane and lateral distance to risk situation within the 100m distance of risk situation were the measurements used to analyze the influence of dual tasks. The results indicate that the Mean Lateral Deviation of the experiment group increased and the lateral distance decreased when compared with the control group. This study provides evidence of detrimental effects of dual tasks on lateral performance when approaching risky situations.
